Tools

search_templates

Find Poly-Glot prompt templates by keyword, goal, or plan. Results include whether each template is currently locked for the account.

Parameters: query (string), goal (string), plan ("free" | "pro"), limit (1–24, default 12), uiLanguage (string, default "EN")

get_template

Get a template's fields and prompt body. The source prompt body is returned only when the account is entitled to use the template.

Parameters: name (string, required), uiLanguage (string, default "EN")

build_prompt

Fill an entitled Poly-Glot template with user values. First eligible use starts the 3-day trial. During the active trial, all 1,000+ templates are unlocked; after the trial, template bodies lock unless the account is Pro.

Parameters: name (string, required), values (object), uiLanguage, inputLanguage, outputLanguage (strings, default "EN")

prepare_compare

Prepare one canonical prompt for 2+ AI providers so the user can compare answers side-by-side. Does not call third-party models on the user's behalf.

Parameters: name (string), prompt (string), values (object), providers (array of "chatgpt" | "claude" | "gemini" | "perplexity" | "grok" | "copilot" | "mistral", min 2), uiLanguage, inputLanguage, outputLanguage

get_language_options

Return the 35 supported Poly-Glot UI, input, and AI output languages. Language selection never changes entitlement.

Parameters: uiLanguage (string, default "EN")

get_subscription_status

Return the current Poly-Glot trial or Pro entitlement state and current pricing.

Parameters: none

Translate text between any of the 35 supported Poly-Glot languages.

Parameters: text (string, required), from (string), to (string, required), uiLanguage (string, default "EN")

get_custom_model_capabilities

Return supported BYOM adapter modes, credential policy, network restrictions, and notes about localhost access.

Parameters: adapterMode ("openai-compatible" | "custom-rest"), baseUrl (string), endpoint (string), model (string), apiKey (string, transient), probe (boolean)

run_custom_model

Run a Poly-Glot prompt against a developer-supplied model endpoint. Applies language instructions and respects entitlement checks.

Parameters: adapterMode ("openai-compatible" | "custom-rest"), baseUrl/endpoint (string), model (string), apiKey (string, transient), prompt (string, required), system (string), temperature, maxTokens, uiLanguage, inputLanguage, outputLanguage

prepare_custom_compare
